I write, accordingly, as an advocate for better leadership, an improved democracy in the United States, and more creative and competent management of the public business. Climate destabilization is obviously a world crisis, but I've chosen to narrow my focus to the United States because we are the largest economy on Earth and the largest source of heat-trapping gases in the industrial era, and we have greater leverage than any other country. And for no good reason we were absent without leave until very recently on the largest issue ever on the human agenda. The United States, in other words, is not just another country; it is, rather, the linchpin in the effort to avoid catastrophic global destabilization.
